please show us the client side logs for your case (https://kb.nomachine.com/DT07S00244?s=client%20logs#2). You can attach them here or send to forum[at]nomachine[dot]com, by referencing this topic.February 22, 2023 at 18:58 in reply to: 8.2.3 display not drawing rest of screen #43045
sorry for the delay. I’m not sure this is the same as the known issue, given that you aren’t using a scaled display. Can you reproduce the issue right now or you downgraded the NoMachine server version in the meanwhile? If you can reproduce, would you send us the logs as explained in https://kb.nomachine.com/AR07K00677? You can send them to forum[at]nomachine[dot]com, by referencing this topic. Then please try to disable hardware decoding on the client (Open the session menu -> Display settings -> Advanced options) and hardware encoding on the server (Server settings -> Performance).February 22, 2023 at 18:23 in reply to: Windows client disconnects from Ventura server #43042
Hi Doug, I examined your logs (sorry for the delay). It seems that something is delaying the startup of the session until a timeout is reached, but unfortunately it isn’t clear what exactly. Did you maybe set up the forward of some device through the session? In that case, please try to connect with a newly created connection file. And would you exclude network problems?February 22, 2023 at 17:49 in reply to: Poor picture quality after upgrading to NoMachine 8 #43038
The Mac is an M1 Mini
What model year?
it seems like my hardware and OS should support hardware H264
Yes, it does. The problem is that the hardware encoder doesn’t provide all the capabilities NoMachine relies upon.
That having been said, certain things are still very poorly rendered
Have you tried to increase the display quality in the Display settings panel of the session menu? You can also try to click on the ‘Disable client side post-processing’, in the advanced options.
would a complete re-install still be recommended
Yes, I would do that, just to be sure.February 22, 2023 at 15:01 in reply to: Poor picture quality after upgrading to NoMachine 8 #43033
Hi nxmac, sorry for the delay. We identified 3 issues in your logs, not all dependent on NoMachine, that explain your observations. The first one is that the library used for software H.264 encoding is missing in your NoMachine installation, probably due to a problem occurred during the upgrade. We suggest to uninstall NoMachine completely on the Mac and reinstall it from scratch. The second issue is that the hardware H.264 encoder on the Mac lacks the capabilities needed for encoding by NoMachine. This doesn’t depend on NoMachine but it would be interesting to know the exact model of your Mac and the macOS version. These 2 issues prevented H.264 from being used at all and the VP8 encoder was used as a fallback, resulting in lower quality images. The third issue is a bug in the code responsible for falling back from H.264 encoding failures and it was causing the blanked screen issue. This will be fixed in the next NoMachine update.February 17, 2023 at 18:15 in reply to: Unwanted repeat keypresses #42989
sorry for the delay. What you describe shouldn’t happen normally as NoMachine already suppresses unwanted repeated keys. To investigate further your specific case we would need more info about your setup, in particular we would need to confirm if the server is using X or Wayland. If it’s more convenient for you, we could get such info from the logs. If you are willing to provide them, please follow the instructions in https://kb.nomachine.com/AR07K00677 and send them to firstname.lastname@example.org, by referencing this topic.February 17, 2023 at 17:32 in reply to: No hardware decode on Kubuntu 22.04 + GTX 1060 6GB #42987
Hi Piter, sorry for the the late reply.
Isn’t the problem related to the drop of vdpau-va-driver by Debian?
Yes, it seems so. Anyway this isn’t something that can be fixed in the NoMachine software.January 24, 2023 at 18:01 in reply to: “Resize Remote Display to Client Window” on OS X to headless EC2 Linux #42685
the “non-working” case occurs when NoMachine detects that there is already a X session running on the systems and it attaches to it. The fact this X session has a limited set of resolutions doesn’t depend on NoMachine.
The “working case” is when NoMachine doesn’t detect a X server already running on the system and creates its own virtual display. The fact a X server is running or not also doesn’t depend on NoMachine.
However you can work around this problem by stopping the display manager and so avoiding a X session is created in all cases. To do so, you can follow the instructions at point 3 of this article:January 24, 2023 at 14:54 in reply to: No hardware decode on Kubuntu 22.04 + GTX 1060 6GB #42677
can you show us the output of these two commands?
for DEVICE in /dev/dri/* ; do echo "*** Trying $DEVICE ***" && LIBVA_DRIVER_NAME=nvidia vainfo --display drm --device $DEVICE ; done
lsmodJanuary 24, 2023 at 10:15 in reply to: Screen frozen when monitor is off #42671
recent Windows versions have an optimization that disables rendering when the monitor is turned off, and this doesn’t depend on NoMachine. You can try to add the following option to the ‘C:\Program Files\NoMachine\etc\node.cfg’ file, even though I’m not sure it will work if the monitor is turned off by the power button:
DisplayServerExtraOptions "-displayrequired 1"
You may also try to change the screen capture method in NoMachine by specifying the following option (the two options can also be concatenated):
DisplayServerExtraOptions "-nodxgigrab"January 12, 2023 at 16:40 in reply to: No hardware decode on Kubuntu 22.04 + GTX 1060 6GB #42450
Please try to installe the ‘vdpau-va-driver’ package and tell us if it helps.January 10, 2023 at 12:49 in reply to: CapsLock won’t turn off #42401
to confirm the issue you are reporting is the same that was reproduced in our labs, please answer the questions below.
Does the temporary workaround suggested by Britgirl work also in your case?
And can you try to press Capslock twice when the issue occurs? Does this also help?January 10, 2023 at 12:42 in reply to: No hardware decode on Kubuntu 22.04 + GTX 1060 6GB #42400
logs show that DRM initialization fails, maybe due to some missing package. Please show us the output of this command:
dpkg -l | grep -i "libva\|vaapi\|vdpau"January 3, 2023 at 10:26 in reply to: Can’t connect to the NoMachine server after moving to a new server #42275
please try to run this command on the server machine and tell us if it reports any error:
sudo /etc/NX/nxserver --eglcapture yes
Then restart the display manager and the NoMachine server to make changes effective:
sudo systemctl restart display-manager sudo /etc/NX/nxserver --restart
Let us know if that solves the problem.December 27, 2022 at 11:00 in reply to: Screen on client side blurs everytime I scroll #42148
Thank you for the report! It seems that what you were seeing is the expected behaviour. By default NoMachine uses progressive refinement of the image quality (what is called ‘multi-pass encoding’ in the option) in order to achieve the minimum response time. Alternatively to disabling those options, you may try to increase the display quality. This will make the progressive refinement quicker.
